Lockable switching positions:
● Position OFF (O)
When the door mounted rotary operator or the side wall mounted rotary operator is
locked in the OFF (O) position, the molded case circuit breaker cannot be closed, nor can
the cubicle door be opened. The door interlock cannot be overridden.
● Position ON (I)
Possible only if the door mounted rotary operator or the side wall mounted rotary operator
has been modified accordingly during installation.
Note
No impairment of protection functions
Locking the rotary operators in the ON (I) position does not impair the protective functionality
of the molded case circuit breakers. In the event of a fault, the molded case circuit breaker
trips in the normal way.
When the rotary operator is unlocked, the switching position changes to TRIP.
